Medical Ultrasound Penetration Depth

The principle of ultrasound - Echopedia

https://www.echopedia.org/wiki/The_principle_of_ultrasound

So for a 10 MHz transducer, the maximum penetration would be as follows: 1 dB/cm/MHz x 10 MHz x (2 x max depth) = 65 dB. Max depth = 65/20 = 3.25 cm. If we use a 3.5 MHz transducer and apply the same formula for max depth, will get Max depth = …
